Abstract

An antenna module and a base station system are disclosed. The antenna module may transmit an electromagnetic wave of a specific frequency band. The base station system includes: a signal tower, a first antenna module, and a second antenna module. The first antenna module and the second antenna module are separately fixed at the signal tower, and share a same antenna installation platform on the signal tower; a distance between a center point of the first antenna module and the signal tower is less than a distance between a center point of the second antenna module and the signal tower. The solutions can enable the base station system to implement multi-band coverage. The first and second antenna modules in the system can operate independently without affecting each other, and can be mounted and disassembled separately.
